Around June or July I built a new computer and decided to go with the Windows 7 64-bit RC after hearing really good things about it. I'm getting the retail full version of Windows 7 Pro for xmas and was wondering how to go about going from RC to Retail. Am I going to have to do a clean reinstall? (losing all my installed programs/settings/etc.)? Or is there a way I can just insert a serial key that comes with the retail copy and it will "activate" my RC to retail so to speak? Any help on the matter would be greatly appreciated, because I (stupidly) didn't really think ahead when I decided to go with the RC and am worried that I screwed myself in having to totally redo my computer after finally getting things how I want them...
